The high court heard arguments Thursday from attorneys who presented a variety of solutions for the bill. The legislation changed campaign finance laws, gave greater powers to the Missouri Ethics Commission, allowed the state Office of Administration to handle contracting bids for elected officials, and gave each lawmaker a key to the Capitol dome.

A lower court previously struck down most of the bill because it contained multiple subjects, allowing to stand only the provisions about government contracting.

A plaintiffs' attorney argued Thursday that the entire bill should fail.

A state attorney countered that the ethics and campaign finance provisions should be allowed to stand.
